How to install a specific JDK on Mac OS X? Ask Question. The explanation is that JDK is a bit specific and does not contain the library tools.jar. For my development, I need this library and Mac's JDK doesn't provide it. If you need Java 6 you must have a 64-bit Intel computer. You should always have Java 5 and 1.4 and perhaps 1.3.

What exactly is Java's new helper tool? The helper tool is an application used to install Java. For the past couple of releases, Oracle has used a standard installer package to install Java 8.

With the release of Java 8 Update 65 though, Oracle returned to using an application to install Java. Oracle’s Java 8 Update 65 install application has the following behavior: This application will prompt for admin privileges before fully launching. Once you provide admin authentication, the application launches.

First, to understand what is causing the issue, one or more applications (you knowprograms, in oldspeak) on your Mac are calling for Java and not finding it (or at least not recognizing it). This most often happens with Macs that have been updated or upgraded to a newer flavour of OS X 10 (usually Yosemite, El Capitan, or Sierra; also known as OS X 10.10, 10.11, and 10.12, respectively) or that came with an OS X 10+ installed. So, you think (reasonably enough) that the issue must be that your Java install isn’t updated (enough) for the new OS version. And that’s where you’d be wrong. Because in reality, what is happening is that the application or applications that are throwing the error are actually looking for an older, legacy version of Java, and not finding it! Specifically, it is looking for the legacy Java 6.

So, to fix the error, you need to download and install Java 6, also known for these purposes as Java for OS X 2015-001. Fortunately, Apple has made this easy, as they recognize their screw-up in shipping apps that still rely on a deprecated (i.e. Discontinued) version of Java. Also fortunately, installing the older version does not seem to impact any programs relying on the newer version, at least in our experience. To download this legacy version of Java, to fix the “To use the java command-line tool you need to install a JDK” error, go here: At the top of the page at that link, you will see this: Just click on ‘Download’, and you will have quickly fixed the issue.
